Question

The volume V of a tumor that commonly develops in canines is directly proportional to the cube of the time t that the tumor has been growing. If a 3-month old tumor has a volume of 1.89 cm3, what will be the size of a tumor that is 4 months old?

Answer 1

Vt^3=some constant k
(1.89)(3)^3=k = 51.03
51.03=Vt^3 = V(64)
V=51.03/64=.797 cm^3

Answer 2

options are 4.48cm^3, 3.48cm^3, 4.84cm^3 or 4.40cm^3

Answer 3

oooh i may have done that backwards. directly proportional.
V/t^3=k
1.89/27=k=.07
.07=V/64
V=.07*64=4.48

Answer 4

my apologies
